Record of Magdalis exarata in the arid floodplain near Grißheim (South Baden)

0

On May 26th, 2012, one specimen of the weevil Magdalis exarata was found in the arid floodplain of Grißheim on oak by using a beating tray. Typical for representatives of the subgenus Neopanus, the scutellum of M. exarata declines towards the base of the elytra and does not fill its cavity. Contrary to the more common sister species M. cerasi, the scape is short. The stenotopic, xerophilous species lives in warm and dry sparse oak forests. In Germany M. exarata is regarded as endangered (RL 2).

Record of Cryptocephalus schaefferi on the Heimberg near Waldböckelheim

1

On May 19th, 2012, numerous specimens of the leaf beetle Cryptocephalus schaefferi were found on the Heimberg near Waldböckelheim. The stenotopic, xerothermophilous species is known to occur in Southern and Central Europe and prefers habitats with warm climate. It is polyphagous and is found on hawthorn (Crataegus), oak (Quercus), hazel (Corylus) and (Sorbus) European rowan (Sorbus). The species exhibits a marked sexual dimorphism. In Germany, recent records are known from the southern part, and the species is regarded as endangered (RL 2).

On May 19th, 2012, several specimens of the leaf beetle Lachnaia sexpunctata were found on the Heimberg near Waldböckelheim. The stenotopic, xerothermophilous species prefers warm and dry slopes and sun-exposed edges of forests. It is polyphagous and can be found from May to July mainly on sun-exposed oaks. The male exhibits conspicuous large legs and tarsi. In Germany, recent records are confined to the southern part, and the species is regarded as endangered (RL 2).

Record of Phytobaenus amabilis in the forest Bienwald near Scheibenhardt

0

On May 17th, 2012, one specimen of the antlike leaf beetle Phytobaenus amabilis was found in the forest Bienwald near Scheibenhardt by using a beating tray on a willow (Salix sp.). The Eurosiberian species is known to occur from Europe to Japan und develops in rotting wood. It was first discovered in 2008 in the Bienwald. Otherwise only old records (before 1950) exist from Brandenburg and Thuringia. In Germany the species is very rare and currently classified as RL 0 (missing).

On March 17th, 2012 three females of the blister beetle Meloe decorus were observed on the Rhine dam near Oberhausen-Rheinhausen (Baden-Württemberg). The place of discovery is located nearby the former population in the vicinity of Philippsburg. This population was presumably extinguished in 2006/2007 by the building activity "Rheinhochwasserdamm HWD XXXIII". The last record was made by C. Wurst in 2002. Hence, there are now recent observations from Baden-Württemberg, the Palatinate, Hesse and Thuringia. Meloe decorus is critically endangered (RL 1).

1

On June 5th, 2011 one specimen of the jewel beetle Coraebus undatus was discovered on the southwest slope of the Heimberg near Waldböckelheim (Nahe valley) on a sun-exposed oak by using a beating tray. The species is of holomediterranean distribution and reaches the northern border of its range in Germany. Coraebus undatus is thermophilous and develops under the bark of trunks and large branches of oak. The development cycle is thought to take 2 or 3 years. Due to its rarity, the species does not have any relevance for forestry in Germany. On the contrary, Coraebus undatus is regarded as endangered (RL 2).

On June 2nd, 2011 six specimens (3 males, 3 females) of the rare apionid weevil Omphalapion laevigatum were recorded near Stutensee-Spöck on corn chamomile (Anthemis). Especially the females are quite conspicuous with their relatively large size within the genus. They can be only confused with the even rarer O. buddebergi. The species is distributed throughout Europe, but generally rare and prefers extensive arable land and warm, sandy ruderal sites. In Germany it is regarded as endangered (RL 2).

On May 29th, 2011 one female specimen of the very rare apionid weevil Omphalapion buddebergi was discovered on the Gangelsberg near Duchroth. The species develops in Yellow Chamomile (Anthemis tinctoria), which grows in xerothermic habitats, e.g. neglected and xeric grassland. Omphalapion buddebergi can be distinguished from similar representatives of the genus by the very long snout and the sculpture of the pronotum. In Germany, the species is very rare with records from Bavaria, the Palatinate, Hesse, Rhineland, Thuringia and Saxony-Anhalt. It is regarded as endangered (RL 2).

The stenotopic, thermophilous species prefers calcareous grassland and heathland. It develops in Scotch Broom (Cytisus scoparius) and is normally found on ailing plants. With a body length of 3.7-4.5 mm A. mendizabali is among the smaller representatives of the genus, and could be confused with A. funerula (not present in Germany).

Record of Ceratapion basicorne near Stutensee-Spöck

0

On May 15th, 2011 two specimens of the apionid weevil Ceratapion basicorne were found near Stutensee-Spöck on the edge of extensive arable land by using a beating tray on cornflowers (Centaurea cyanus). Its distribution ranges from Europe and North Africa to Asia Minor. Due to the land consolidation and intensification of agriculture during the recent decades the acreage of extensive arable land with its segetal flora and specialized beetle fauna has declined tremendously. Consequently, Ceratapion basicorne is regarded as endangered in Germany (RL 2).

On May 14th, 2011 one specimen of the ground beetle Stenolophus skrimshiranus was observed at the edge of a nearly dried-out pond (continued drought in spring 2011) in the nature reserve Bruchgraben near Baden-Baden-Oos. Stenolophus skrimshiranus is the rarest of the three species of the genus in Germany. Its distribution ranges from France and England over Central and Eastern Europe to Central Asia. The beetle is normally found on muddy edges of ponds. Although there are recent records from virtually all Federal States in Germany, Stenolophus skrimshiranus is recorded only occasionally and is regarded as endangered (RL 2).
